Magma pressure can bring earth to explode

If a super volcano erupts , the consequences for the climate and life are devastating. Researchers have found , as it can lead to such a disaster .Scientists have analysed the molten rock within the dormant supervolcano beneath Yellowstone National Park and found that eruption is possible without any external trigger.

Scientists previously believed many supervolcanic eruptions needed earthquakes to break open the Earth’s crust so magma could escape. But new research suggests that this can happen as a result of the build-up of pressure.

Supervolcanoes represent the second most globally cataclysmic event – next to an asteroid strike – and they have been responsible in the past for mass extinctions, long-term changes to the climate and shorter-term “volcanic winters” caused by volcanic ash cutting out the sunlight.
